Do repeat radiological procedures on the same patient increase the radiation risk?
Yes. Radiation effects are known to be cumulative in nature. However, the repair mechanisms in the body are quite active and spacing the procedures with suitable time intervals helps reduce radiation effects, as is done in radiotherapy. At the moment there is no formal mechanism to record and track cumulative radiation exposure to a patient, as is done for staff. Patients are advised in their own interest to let all physicians know about their previous radiological examinations.
